Abstract

A bidirectional electric fan is composed of a drive axle with a gear at its middle point, two blade wheels fixed to both ends of said drive axle, and a motor with a gear engaged with that on drive axle.

Description

Two side electric fan

Technical field the present invention relates to a kind of domestic electric appliance, especially a kind of can be comprehensive the two side electric fan of large size blowing.

Technical background is present, and electric fan is one of household electric appliance of having popularized, during the broiling summer or under the airless situation, uses electric fan can effectively accelerate air ventilation, and the performance blowing is avoided heat and got rid of effect such as peculiar smell.Generally speaking, present electric fan has a great variety of models, function is different, advantages such as pattern is attractive in appearance, some electric fan has more some other miscellaneous functions, for example regularly, illumination, fragrant etc., but all there is a common shortcoming in all at present electric fans, that is exactly that the maximum rotating range of yaw of electric fan can only be within 180 °, briefly, electric fan is placed in indoor central position allows its blowing work, and indoorly can only have at most the space of half can directly accept wind, other spaces then can only between receive wind, thereby make working space be affected, form many winds less than dead-space volume, it is very inconvenient to allow people use, and can not satisfy many people and use simultaneously.For fear of the generation once more of this class problem, provide a kind of have two groups of flabellums, can comprehensive blowing new-type electric fan certain social and economic implications appear having.

Summary of the invention the purpose of this invention is to provide a kind of two side electric fan, is used to solve the problem that the common electrical fan can't carry out comprehensive rotation blowing.

For achieving the above object, two side electric fan of the present invention comprises two groups of flabellums, motor, rotatingshaft, dwang and supporting frame shell, at the point midway socket gear of rotatingshaft, and gear parallels with the transversal plane of rotatingshaft, and rotatingshaft evenly stretches out before and after supporting frame shell top; The flabellum that connects respectively separately on two tops of rotatingshaft makes up; The shaft of motor top also is equipped with gear, the mutual interlock of gear and gear.

After adopting said structure, the user only needs the control switch of closed motor, the motor work that will begin in a minute, the gear that machine shaft drives its top rapidly rotates, because the mutual interlock of gear on the gear on the motor rotary shaft and the fan shaft at supporting frame top, therefore can drive the also rapidly rotation simultaneously of rotatingshaft of supporting frame inside, at this moment, rotatingshaft also can drive the flabellum combination rotation blowing that is installed in two ends, left-right rotation by supporting frame again, make the blowing simultaneously in the opposite direction of two groups of flabellums to enlarge the blowing space, increase beneficial effect.

Advantage of the present invention is: simple in structure, easy to use, cheap, be widely used, beautiful shape, can also increase the blowing space effectively by the time effect of two groups of flabellums, be particularly suitable for many people and use simultaneously, and can guarantee 360 ° of comprehensive wind-engagings.

Description of drawings Fig. 1 is the overall structure schematic representation of two side electric fan of the present invention.

Embodiment as shown in Figure 1, two side electric fan of the present invention, comprise two groups of flabellum 1-1,1-2 motor 2, rotatingshaft 3, dwang and supporting frame shell, point midway socket gear 4-1 at rotatingshaft 3, and gear 4-1 parallels with the transversal plane of rotatingshaft 3, and rotatingshaft 3 evenly stretches out before and after supporting frame shell top; The flabellum that connects respectively separately on two tops of rotatingshaft 3 makes up 1-1,1-2; The rotating shaft top of motor 2 also is equipped with gear 4-2, gear 4-1 and the mutual interlock of gear 4-2.When using, the user only needs the control switch of closed motor 2, motor 2 work that will begin in a minute, the gear 4-2 that motor 2 rotating shafts drive its top rapidly rotates, because gear 4-2 and the mutual interlock of gear 4-1 in motor 2 rotating shafts, therefore can rotate by driven gear 4-1, because gear 4-1 is installed on the rotatingshaft 3, therefore can drive also rapidly rotation simultaneously of rotatingshaft 3, at this moment, rotatingshaft 3 drives the flabellum 1-1 and the flabellum 1-2 that are installed in two ends and rotates blowing simultaneously, left-right rotation by supporting frame again, make the blowing simultaneously in the opposite direction of two groups of flabellums to enlarge the blowing space, increase beneficial effect.

Claims

1, a kind of two side electric fan, comprise flabellum (1-1), motor (2), rotatingshaft (3), dwang and supporting frame shell, it is characterized in that: at the point midway socket gear (4-1) of rotatingshaft (3), and gear (4-1) parallels with the transversal plane of rotatingshaft (3), and rotatingshaft (3) evenly stretches out before and after supporting frame shell top; The flabellum that connects respectively separately on two tops of rotatingshaft (3) makes up (1-1), (1-2): the rotating shaft top of motor (2) also is equipped with gear (4-2), gear (4-1) and gear (4-2) interlock mutually.
